Description

Technical Field

[0001] This utility model belongs to the field of metal smelting technology, and in particular to a steel tapping mechanism for a vacuum furnace used in alloy smelting. Background Technology

[0002] When pouring steel ingots at a fixed point in a vacuum furnace, the steel tapping trough is usually placed on a support base of appropriate height to receive the molten steel, and then poured downwards into the mold for ingot pouring. Different height specifications of steel ingots require molds of different heights.

[0003] Currently, when casting ingots of different heights, different height supports are generally used to adjust the height of the tapping trough to ensure smooth connection between the vacuum furnace, tapping trough, and mold. However, this method is not only costly, but also has a limited number of support heights available, sometimes still unable to match various new ingot heights. Therefore, how to achieve a smooth connection between the vacuum furnace, tapping trough, and mold when casting steel ingots of different heights in an economical and convenient manner has become a problem that needs to be solved. Utility Model Content

[0019] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Please refer to Figure 1 and Figure 2 A steel tapping mechanism 100 for a vacuum furnace used in alloy smelting includes a steel tapping trough 1, a support base 2, a slider 3, and a slide rail frame 4.

[0022] A steel discharge hole 11 is provided at the bottom of the steel discharge trough 1.

[0023] The steel discharge trough 1 is slidably disposed within the support base 2 along the first direction X. The support base 2 includes a base plate 21, a first side baffle 22, a second side baffle 23, a third side baffle 24, and a fourth side baffle 25. The first side baffle 22, the second side baffle 23, the third side baffle 24, and the fourth side baffle 25 are sequentially arranged around the base plate 21. The first side baffle 22 and the third side baffle 24 have a first spacing in the first direction X, and the second side baffle 23 and the fourth side baffle 25 have a second spacing in the second direction Y. A through square hole 211 is provided at the center of the base plate 21. The length of the square hole 211 in the first direction X is equal to the first spacing, and the width of the square hole 211 in the second direction Y is greater than the inner diameter of the steel discharge circular hole 11 and less than the second spacing. The width of the steel discharge trough 1 in the second direction Y is equal to the second spacing.

[0024] The slider 3 is fixed on the third side stop 24 on the side away from the first side stop 22.

[0025] The slide rail support 4 includes a slide rail groove 41 extending vertically along the third direction Z. The slider 3 is slidably embedded in the slide rail groove 41 along the third direction Z, and the slider cannot move along the first direction X and the second direction Y. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. The mold 101 and the slide rail support 4 can generally be placed upright normally. In this way, the mold serves as a support on one side and the slide rail support serves as a support on the other side. The two work together to keep the support base and the equipment as a whole stable, so as to achieve safe material discharge.

[0026] Optionally, the steel tapping mechanism 100 of the vacuum furnace for alloy smelting also includes a fixed base 5, which is fixedly installed on the ground 102 and located below the steel tapping trough 1. It is used to stably place the mold 101, and the bottom of the slide rail stand 4 is fixed to the ground 102 by bolts. In this way, the mold 101 and the slide rail stand 4 are more stable and less likely to tip over, which can better achieve safe material tapping.

[0027] Optionally, the cross-sectional shape of the slider 3 perpendicular to the third direction Z is trapezoidal, and the end face of the slider 3 connected to the third side stop 24 is smaller than the end face of the slide rail 3 embedded in the slide rail groove 41. This arrangement prevents the slider from moving in either the first or second direction.

[0028] Optionally, the slider 3 and the third side stop 24 can be integrally molded. This results in a smoother connection between the slider and the third side stop.

[0029] Optionally, the first side guard 22, the second side guard 23, the third side guard 24, and the fourth side guard 25 are sequentially arranged around the top surface of the base plate 21. This reduces the height of the four side guards and saves materials.

[0030] Optionally, the top surface of the third side baffle 24 is higher than the top surface of the first side baffle 22. This arrangement not only enhances the overall stability of the support base but also effectively prevents the vacuum furnace from hitting the first side baffle when it tilts.

[0031] Preferably, the top surface height of the second side guard 23 and the fourth side guard 25 gradually increases upward along the first direction X.

[0032] Optionally, the second side guard 23 and the fourth side guard 25 have the same shape and size. This arrangement facilitates manufacturing.

[0033] Optionally, the top of the steel discharge trough 1 is provided with an opening 12 that is wider at the top and narrower at the bottom, and the lower part of the opening 12 is connected to the steel discharge hole 11. This facilitates the steel discharge trough to receive material at the wide opening and discharge material at the narrow opening.

[0034] Optionally, the bottom surface of the base plate 21 is flush with and perpendicular to the third direction Z. This facilitates the stable placement of the support on the top surface of the mold.

[0035] The operating principle of the steel tapping mechanism 100 of the vacuum furnace for alloy smelting according to an embodiment of this utility model:

[0036] Before the vacuum furnace is tilted and poured, the support base 2 and the slider 3 are raised along the slide rail groove 41 in the third direction Z to the height of the slide rail stand 4 until they are higher than the height of the mold 101 to be poured. The mold 101 to be poured is placed below the base plate 21. Then the support base 2 is lowered to the top surface of the mold 101. Then, when the vacuum furnace is tilted, the steel trough 1 is slid out along the first direction X to a suitable position to receive the molten steel poured out of the vacuum furnace. The molten steel flows into the mold 101 through the steel outlet round hole 11 and square hole 211 for pouring.

[0037] The steel tapping mechanism of the vacuum furnace for alloy smelting of this utility model can economically and conveniently achieve smooth connection between the vacuum furnace, the tapping trough and the mold when casting steel ingots of different heights and specifications, which greatly saves costs, reduces space occupation and greatly improves the accuracy of connection.

[0038] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
